-- A geofence geometry is made up of either a polygon or a circle. Can be
-- either a polygon or a circle. Including both will return a validation
-- error.
--
-- Amazon Location doesn\'t currently support polygons with holes,
-- multipolygons, polygons that are wound clockwise, or that cross the
-- antimeridian.

    -- or an array of arrays of doubles (@[[double, double], ...]@).
